PayTm is now one of the biggest startups of India due to its increased fan following which is obviously due to their hardwork. After the demonetization of 500-1000 notes, Paytm has became very popular in India and is now used by almost half of India. Their customer service is very nice. Their customer care number is 09643979797. They are available 24/7 hours a week on this number. Usually the product quality of them is good and delivers within the expected time. The new Paytm app is super fast and gives a very good response so I would like to recommend you all to use Paytm.
